USED DMG MORI KBT 13 A

The DMG MORI KBT 13 A is a large-capacity horizontal boring and milling machine designed for heavy-duty machining of oversized industrial components. It is part of the KBT 13 series, which is known for its high rigidity, strong torque output, and ability to handle large and complex workpieces in industries such as power generation, shipbuilding, heavy machinery, and structural engineering.

The machine provides a substantial working envelope with axis travels of approximately 3,000 mm in X, 2,000 mm in Y, and 1,300 mm in Z, allowing it to machine very large components in a single setup. The table size is around 1,800 × 2,200 mm, with a maximum load capacity of up to 15,000 kg, making it suitable for heavy castings and large steel fabrications.

A key feature of the KBT 13 A is its 130 mm diameter high-torque boring spindle, supported by a rigid three-point bearing structure. The spindle delivers extremely high torque—around 5 to 8 times higher than conventional machining centers—making it ideal for deep boring, heavy roughing, and large-scale milling operations.

In terms of cutting time, the machine is optimized for sustained heavy material removal rather than high-speed finishing. Its W-axis machining system reduces the mass being moved during operations, which significantly lowers energy consumption and improves machining efficiency. This results in about one-third lower energy usage in drilling cycles and nearly half in tapping cycles, especially in repetitive production runs.

Machines typically use FANUC or CELOS control systems, focusing on reliability, torque stability, and long-term durability. Overall, the KBT 13 A is built for maximum rigidity, high load capacity, and continuous heavy-duty machining performance in demanding industrial environments.

WHY BUY USED DMG MORI KBT 13 A

Buying a used DMG MORI KBT 13 A is a practical decision for industries that require heavy-duty machining of large components. Its biggest advantage is its extremely rigid construction combined with a high-torque spindle system, allowing it to maintain stability and accuracy even after years of operation under heavy cutting loads.

Cost savings are significant. New machines in this category require very high capital investment due to their size, spindle power, and structural reinforcement. A used KBT 13 A provides access to the same industrial machining capability at a much lower upfront cost, improving return on investment for heavy fabrication, energy, and infrastructure sectors.

Older boring machines (pre-2000) typically lack sufficient rigidity and torque for modern large-part machining and often suffer from longer cutting times and instability under load. Machines from 2000 to 2010 improved spindle performance and CNC reliability but still cannot match the efficiency and structural strength of the KBT 13 series.

Used KBT 13 A machines from 2010 onward are particularly valuable because they retain strong structural integrity while benefiting from improved CNC controls, better thermal stability, and more consistent machining performance. The W-axis system also improves efficiency by reducing moving mass, which helps lower energy consumption during long drilling and boring cycles.

From a cutting-time perspective, the KBT 13 A is designed for continuous heavy cutting rather than high-speed cycle reduction. A well-maintained used unit can still deliver high productivity because it removes large volumes of material efficiently in a single setup. Combined with DMG MORI’s global service support, it remains a reliable long-term industrial asset.

HOW MUCH DOES A USED DMG MORI KBT 13 A COST?

The cost of a used DMG MORI KBT 13 A depends on machine condition, year of manufacture, spindle hours, tooling configuration, and maintenance history. As a heavy horizontal boring machine, it falls into a specialized industrial pricing segment.

Older machines comparable to pre-2000 boring mills typically range from $70,000 to $180,000. These machines generally have lower spindle torque, older CNC systems, and longer cutting times, making them suitable only for basic heavy machining tasks.

Machines manufactured between 2000 and 2010 typically range from $180,000 to $350,000. These models offer improved spindle torque, better structural rigidity, and more reliable CNC systems, resulting in more consistent machining performance and reduced downtime.

For KBT 13 A machines produced between 2010 and 2025, prices generally range from $350,000 to $750,000 or more depending on configuration and condition. These newer machines benefit from improved rigidity, advanced CNC controls, better thermal stability, and enhanced process monitoring, making them highly suitable for large-scale industrial production.

Cutting time is not the main pricing factor. Instead, value is determined by torque capacity, structural condition, and the ability to sustain heavy-duty machining over long cycles. Machines with low spindle wear, stable alignment, and well-maintained gearbox systems command higher resale value due to reliability under continuous load.

Overall, the KBT 13 A is a premium heavy-machining investment where durability, load capacity, and stability matter far more than high-speed cycle performance.
